RV4145A Datasheet | Fairchild Semiconductor

.fairchildsemi. Low Power Ground Fault Interrupter Features - - - - No potentiomenter required Direct interface to SCR Supply voltage derived from AC line - 26V shunt Adjustable sensitivity - - - - Grounded neutral fault detection Meets U.L. 943 standards 450µA quiescent current Ideal for 120V or 220V systems Description The RV4145A is a low power controller for AC outlet ground fault interrupters. These devices detect hazardous grounding conditions, such as equipment (connected to opposite phases of the AC line) in contact with a pool of water and open circuits the line before a harmful or lethal shock occurs. Contained internally are a 26V zener shunt regulator, an op...
